IMPROVEMENT lN OlL-STOVES.

Specification forming part of Letters Patent N 0. 211,359, dated January14, 1879; application filed March 23, 1878.

To all whom it may concern:

, Be it known that I, EUGENE It. WALKER, of Chicago, in the county of(look and State of Illinois, have invented certain new and usefulImprovements in Oil-Burning Stoves; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

Similar letters indicate corresponding parts.

The object of my invention is to provide an oil-stove constructed topermit a free circulation of air around the parts containing the oil,whereby it may be kept cool, the generation of gas prevented orlessened, and the danger of explosion obviated.

It consists in certain details of construction and combination,hereinafter more fully described and claimed.

In the drawings, Figure l is a longitudinal vertical section. Fig. 2 isa transverse vertical section. v

A is the oil-reservoir, surrounding an interior air-space, within whichare the wick-receptacles B, connected with the reservoir by feeders oroil-passages E, which may be at the sides or ends of these receptacles.These wickreceptacles are broad at the base, and the sides convergetoward the top, being in form an irregular truncated pyramid. They serveas a base for the wick-tubes O, and are of a capacity to hold a longwick, which may be compactly folded within them. Between thesewick-receptacles and the reservoir is an open space on all sides,permitting the air to circulate freely around them and on all sides ofthe reservoir, thereby presenting the greatest pos sible amount of areafor cooling the oil.

The upper plate of the reservoir is provided at the rear of the stovewith two upright standards, G, having slots in their upper ends for thereception of pivotsI of arms S, attached to the base of drum D, thusforming hinges, whereby the drum may be turned back or removed when itis desired stove.

to light the which the drum rests.

lar feet, a, attached to its base-plate. This A cast-iron plate, K,provided with feet a, resting in sockets in the upper surface of thereservoir, serves as a table or platform, upon The drum D hassimiplatform K is provided with openings, through ,which the wick-tubes(J project into the drum,

and an annular rim or flange, v, corresponding in size and shape tothese openings, extends from the base-plate of the drum into each,securely inclosing the wick-tubes. I usually cover the openings with awire-gauze or thin plate of perforated metal.

The sockets within which the feet a and a rest may be lined with somenon-conducting substance, and thereby prevent the conduction of heatfrom the drum to the oil-reservoir.

The reservoir, oil-passages, and wiek-recep;

tacles are cast in one piece, thus securing strength and economy inconstruction. The bottom plate, which may be of tin or other suitablematerial, is also in one piece, having the necessary openings betweenthe reservoir and wick-receptacles.

The prevention of the generation of gas in the reservoir andwick-receptacles is effected by a constant supply of cool air, whichcirculates freely around and over the large surface covering the oil,and serves to neutralize the heat that is deflected from the burnersupon such surface. It is, however, probable that some gas will be formednotwithstanding this arrangement. This I remove by means of the tubes Fand F, the first of which extends through the upper plate of thereservoir, and

the latter from the wick-receptacles, and conducts the gas thence to theburners, where it is consumed.

In order to further and more effectually guard against explosion, I fillthe oil-passages E with wire-gauze.

When it is desired to operate my invention, the cap 0 is removed and thereservoir filled with oil. The drum D is then turned back or removed andthe wicks lighted,after which the drum is replaced, andthe stove is inoperation.

An ordinary spur-wheel device is used for raising or lowering the wick.

I am aware that an inclosing jacket or shield surrounding the wick-tubehas been used to conduct any gas that may be generated in theoil-reservoir to the burner. Y

I am also aware that an oil-reservoir surrounding an interior space,Within which are located the Wick-tubes, is not new; and I do not claimthem, broadly.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is l 1. The small gas-tubes 1 F, in combination withand extending respectively from the interior of reservoir A andwick-receptacles B to the burners, substantially as described, and forthe purpose specified.

2. The insulated platform K, in combination with the base, oonsistin gof the oil-reservoir A, wick-receptacles B, having the Wick-tubes,feed-pipe E, and gas-tubes F F, and the drum D, all constructedsubstantially as described, and for the purpose set forth.

In testimony that I claim the foregoing as my own invention I atlix mysignature in presence of two Witnesses.
